What kind of idiot would think that anyone would use a permanent

With even more weight and less range. Great.

Anyone who is interested in high torque and high efficiency at relatively
low RPM.
Take a look at the modified high torque, high speed hub motors that are
most commonly used for bicycles for instance. You don't want to drive
wheels directly with a 20,000 RMP motor.

Hobbyests all over the world are doing it. Too difficult for you ay?

Not very, which is why they ultimately won't be used. Molten salt
batteies are most useful for power backup systems. I believe the melting
point of the salt is 260'F, so it's just above the boiling point of water.

With Lithium Ion that would be less weight and longer range. Smegma
Breath.
Back to gas consumption for the moment.
On a long journey of 1,000 km the Italian car magazine "Quattroruote"
measured the fuel consumption of the smart fortwo cdi and confirmed the
standard consumption of 3.3 litres per 100 kilometres.
The current December issue of the magazine carries a report of the test
drive. The smart travelled 1,000 kilometres from Rome to Salzburgon a single
tank of fuel to see whether the stated standard consumption of just 3.3
litres per 100 kilometres could really be achieved.
The route chosen largely consisted of motorways, but there were also detours
and traffic jams because of roadworks, long uphill stretches and city
traffic in Rome, Bolzano and Salzburg.
The result: the smart fortwo cdi travelled the 1,000 km on a single tank of
fuel. This corresponds to average consumption of just 3.3 litres per 100
kilometres i.e. the standard consumption. According to "Quattroruote" this
makes the smart fortwo cdi the vehicle with the lowest average consumption
that the magazine has ever tested in the history of its road tests.
With standard consumption of just 3.3 litres per 100 kilometres and CO2
emissions of just 88 grams per kilometre the smart fortwo cdi is the
production vehicle with the lowest consumption and the lowest carbon dioxide
emissions. For customers this means that at present there is no more
economical and climate-friendly car than the smart fortwo cdi.
